(i)            less than $12.50, then Section 1.9(b) and this Section 1.9(c) shall terminate and no further Sponsor Earnout Shares shall be issuable thereunder or hereunder;

(ii)           greater than or equal to $12.50 but less than $15.00, then, (A) immediately prior to such Change of Control, the Company shall, subject to Section 1.9(g), issue 1,300,000 Company Shares to the Sponsor (less any Sponsor Earnout Shares issued prior to such Change of Control pursuant to Section 1.9(b)(i)-(iii); provided, that such reduction shall not reduce the number of Company Shares required to be issued to a number that is below zero) and (B) thereafter, Section 1.9(b) and this Section 1.9(c) shall terminate and no further Sponsor Earnout Shares shall be issuable thereunder or hereunder;

5

(g)           If, (A) the Company reasonably determines that obtaining any approval of its shareholders or any other approval is required under applicable Law in order to issue Sponsor Earnout Shares pursuant to this Section 1.9, the Company promptly seeks such requisite shareholder or other approval and fails to obtain such shareholder or other approval within six (6) months after the occurrence of the applicable triggering event set forth in Sections 1.9(c)(ii)-(iv), or (B) an issue of Sponsor Earnout Shares is subsequently unwound by order of a Governmental Authority, (collectively “Unissued Sponsor Earnout Shares”), then, the Company shall promptly (and in any event within ten (10) Business Days)) pay an amount of cash to the value of the Unissued Sponsor Earnout Shares calculated based upon a price per Unissued Earnout Share equal to the price per Company Share that gives rise to the relevant triggering event set forth in Sections 1.9(c)(ii)-(iv).

Section 1.10           PFIC. For so long as the Sponsor or any of its direct or indirect owners that are “United States persons” (within the meaning of Section 7701(a)(30) of the Code) own, in the aggregate, at least two percent (2%) of the issued and outstanding Company Shares:

(a)            the Company, in consultation with a nationally recognized accounting firm and at the Company’s expense, shall determine each year whether the Company or any of its Subsidiaries is or likely will become a “passive foreign investment company,” as defined in Section 1297(a) of the Code (a “PFIC”), and shall use commercially reasonable efforts to notify the Sponsor (or its direct or indirect owners that are United States persons if Sponsor is no longer in existence) of this determination within 45 days of the end of each calendar year or as soon as reasonably practicable thereafter (provided that such notice may be provided in any form, including by way of inclusion of a statement in an SEC or other public filing or notice that is publicly accessible on the Company’s website or otherwise); and

(b)           upon a determination by the Company that the Company is or likely will become a PFIC (or if the Company, in consultation with such accounting firm, is unable to make such a determination following good-faith analysis), the Company shall use reasonable best efforts, subject to any restrictions imposed by applicable securities Laws, to provide the Sponsor (or, if Sponsor is no longer in existence, its direct or indirect owners upon request) with, or make publicly accessible on the Company’s website or otherwise, all information reasonably available to the Company with respect to the Company and its Subsidiaries that is reasonably necessary for the Sponsor or such requesting direct or indirect owners to make and maintain a “qualified electing fund” election pursuant to Section 1295(b) of the Code with respect to the Company and any of its Subsidiaries that is treated as a PFIC.
